I’m not understanding what the basis of a complaint against the radiologist might be. Although you can be provided a copy of the radiology report, these specialists do not normally discuss results with a patient. Although they may answer questions during the procedure, the results were ordered by your doctor and that’s who is charged with discussing them with you. If you believe the doctor is blowing your results off, then you’re doing the right thing to seek another opinion. Even in that case, there isn’t much to complain about formally with your current doctor. Right or wrong, he’s entitled to his opinion on your case. I think you’re better served by just seeking other opinions. You have no requirement to email your surgeon about second opinions that you seek and I wouldn’t advise doing that.
